4.
a sipster is an older brother or sister of a hipster; women and men in their 30's who generally listen to indie rock, hang out in coffee shops, shop at the thrift stores and talk about things like books, music, films and art with a wealth of life experiences; a confident, bawdy and bold woman in her 30's.
That woman with the perfectly groomed nails, holding a cigarette and pint of insert name of microbrew here is a sipster.
